Hardness Test on Hair by DUH-211S Ultra Micro Hardness Tester

Introduction

People's hair is subjected to various external damage daily. Various factors cause hair to be impaired or damaged. Of these, it is said that friction, heat and hair treatment such as poor haircuts and perms account for most of these factors. In this test, we tried evaluating hair by "hardness" that had deteriorated, in particular, as a result of being treated with chemicals, and hair, on the other hand, that was not treated by any artificial means. The "Shimadzu DUH-211S Ultra Micro Hardness Tester", which is compatible with the measurement of micro objects, was used for measuring hardness.
